The rate at which the ball drops from the height is an illustration of an geometric sequence
The height of the 9th bounce of the ball is 0.4 feet
How to determine the height of the ballThe given parameters are:
Initial height, a = 4.75
Rate, r = 75%
Bounce, n = 9
The function that represents the height of the ball is:
[tex]H = ar^{n[/tex]
So, we have:
[tex]H = 4.75 * (75\%)^{9[/tex]
Evaluate
[tex]H = 0.4[/tex] --- approximated
Hence, the height of the 9th bounce of the ball is 0.4 feet

What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
Renaldo has a budget of $500 to buy gift boxes for a party. Large boxes cost $65 and small boxes cost $35.
Let 'x' be the number of small boxes and 'y' be the number of large boxes. Then the inequality is written as,
35x + 65y ≤ 500
If Renaldo buys 5 small gift boxes. Then the number of large gift boxes will be given as,

The stadium has two tiers of spectator seats and VIP seats. The number of VIP seats is 1/12 of all seats. The ratio of the number of 1st tier seats to the number of 2nd tier seats is 7:5. If there are 600 VIP seats, how many 1st tier seats are in the stadium?
Answer:
350
Step-by-step explanation:
350 because there are 1/12 of VIP seats and there are 600 so 600 times 1/12 is 6,600.
Then you minus off the 600 VIP seats so you get 6000
next you do 600 divided bu 12 because of the 1st tier seats and 2nd tier seats combined which then you get 50
lastly you do 50 times 7 because of the ration 7:5 1st tier seats to 2nd tier seats so then you get 350

Solve the following variation problem
The interest on an investment varies directly as the rate of interest.
If the interest is $49 when the interest rate is
4%, find the interest when the rate is
7.7%
Answer:
$94.325
Step-by-step explanation:
Given interest (I) varies directly as rate of interest (R) then the equation relating them is
I = kR ← k is the constant of variation
To find k use the condition I = 49 when R = 4 , then
49 = 4k ( divide both sides by 4 )
12.25 = k
I = 12.25R ← equation of variation
When R = 7.7 , then
I = 12.25 × 7.7 = $94.325

a) A bus traveled 288 km in 4 hours.
b) A fish swam 75 m is 25 s.
c) Seven lemons cost $1.40.
d) $250 for a 5-day car rental.
Answers:
a) 72 km per hourb) 3 meters per secondc) 0.20 dollars or 20 cents per lemond) 50 dollars per day====================================
Explanation:
a) Divide the distance over time to get the unit rate, which is the speed in this case. Speed = distance/time = 288/4 = 72 km per hour. b) Like before, divide the distance over time to get 75/25 = 3 meters per second.c) We want the cost of 1 lemon. So we'll divide the total cost over 7 to get (1.40)/7 = 0.20 dollars = 20 cents per lemond) Divide the total cost over the 5 day period. This will get the cost of each day. So we have a unit cost of 250/5 = 50 dollars per day.HELP HOW DO I SOLVE THIS

square DEFG is inscribed in equilateral triangle ABC with a side length of 3+2√3.
Find: area of the square
Answer:
9 units²
Step-by-step explanation:
**Refer to the attached diagram**
The angles in the right triangle FAD (and HBE) are 30-60-90 which means that its sides will be in the ratio 1 : √3 : 2
Let x = the smallest side
Therefore, the sides of the right triangle FAD are in the ratio x : √3x : 2x
This means that:
the side length of the square = √3xthe side length of the triangle = x + √3x + x = (2 + √3)xWe are told that the side length of the triangle is 3 + 2√3, so:
[tex]\implies 3 + 2\sqrt{3} =(2 + \sqrt{3} )x[/tex]
[tex]\implies x=\dfrac{3 + 2\sqrt{3}}{2 + \sqrt{3} }[/tex]
[tex]\implies x=\sqrt{3}[/tex]
As the side length of the square is √3x, and x = √3,
⇒ side length of the square = √3 x √3 = 3
Now we know the side length of the square, we can calculate the area:
⇒ area of a square = side length x side length = 3 x 3 = 9 units²

$9,800.00 is invested at an annual rate of 11.6%, compounded continuously. How long will it take for that investment to grow to a value of 149,000.00? Round your answer (in years) to two decimal places at the END of your calculations.
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 3.875/100
r = 0.03875 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 10,000.00(1 + 0.03875/12)(12)(7.5)
A = 10,000.00(1 + 0.003229167)(90)
A = $13,366.37
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $10,000.00 at a rate of 3.875% per year compounded 12 times per year over 7.5 years is $13,366.37.

Re-write the quadratic function below in Standard Form
y= 2(x - 2)2 – 7
Answer:
Standard form: y = 2x² - 8x + 1
Step-by-step explanation:
We are given the following quadratic function, y = 2(x - 2)² - 7, for which we must transform in its standard form.
Definition: Quadratic Function in Vertex Form:The vertex form of a quadratic function is y = a(x - h)² + k (which is the format of the given equation).
The vertex of the parabola occurs at point (h, k). The value of "a" determines the direction of the graph's opening (reflection across the x-axis); it also indicates the wideness or narrowness of the graph (vertical stretch or compression).⇒ If the value of "a" is positive, then the vertex is its minimum or lowest point on the graph.
⇒ If the value of "a" is negative, then the vertex is the maximum or highest point on the graph.
Quadratic Function in Standard Form:The standard form of a quadratic function is y = ax² + bx + c, where a ≠ 0.
Solution:Step 1: Expand the binomial, (x - 2)²:
The first step in rewriting the given equation into its standard form is expanding the binomial using the FOIL method, which transforms it into a perfect square trinomial.
y = 2(x - 2)² - 7
⇒ (x - 2)(x - 2)
⇒ [ x² - 2x - 2x + 4 ]
Step 2: Substitute the perfect square trinomial into the vertex form:y = 2(x - 2)² - 7
y = 2(x² - 2x - 2x + 4) - 7
Step 3: Distribute "2" into the parenthesis:y = 2(x² - 2x - 2x + 4) - 7
y = 2x² - 4x - 4x + 8 - 7
Step 4: Combine like terms and constants, then simplify:y = 2x² - 8x + 1.
Final Answer:Therefore, the quadratic function in standard form is y = 2x² - 8x + 1, where a = 2, b = -8, and c = 1.

∘
. Find the distance from point AA to point BB. Round your answer to the nearest foot if necessary.
The distance from point A to B is 2723.8 feet.
Trigonometric ratioTrigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let h represent the height of the light house, hence:
tan(9) = h/1347
h = 213.3 feet
Let d represent the distance from point B to the lighthouse base, hence:
tan(3) = 213.3/d
d = 4070.8 feet
Distance from point A to B = 4070.8 feet - 1347= 2723.8 feet.

A 3-column table with 5 rows. The first column has entries empty, distance travelled (meters), time (initial) (seconds), time (final) (seconds), elapsed time (seconds), average speed (meters per second). The second column labeled Trial A has entries 4. 0, 2. 0, 2. 5, 1. 5, 2. 7. The second column labeled Trial B has entries 4. 0, 1. 5, 4. 5, empty, empty. Use the data table on the left to complete the calculations. What is the elapsed time for Trial B? s What is the average speed for Trial B? m/s.
Speed is the ratio of distance and time
The elapsed time is 3 secondsThe average speed is 1.33 meters per secondHow to calculate the elapsed timeThe elapsed time is the difference between the final time and the initial time.
So, we have:
Time elapsed = 4.5 seconds - 1.5 seconds
Evaluate the difference
Time elapsed = 3 seconds
Hence, the elapsed time is 3 s
How to calculate the average speedThe average speed is the quotient of the distance and the elapsed time.
So, we have:
Average speed = 4 meters/ 3 seconds
Evaluate the quotient
Average speed = 1.33 meters per second
Hence, the average speed is 1.33 m/s
